Explain briefly about longitudinal wave & Transverse wave?
Longitudinal Wave | Transverse Wave |
Longitudinal waves are those in which the particles of the medium oscillates parallel to the propagation of the wave. | Transverse waves are those in which the particles of the medium oscillates perpendicular to the direction of the wave. |
Longitudinal wave always needs a medium to propagate. These are mechanical waves. Wave propagating along the length of a spring is a longitudinal wave. Sound wave is a longitudinal wave. | Transverse wave that needs medium to propagate is a mechanical wave. Water waves (formation of ripples in a pond) are transverse waves. Electromagnetic waves (example: light) are also transverse waves (electric and magnetic field oscillates perpendicular to the propagation of the wave) but these waves don't need a medium to propagate. |
